How do you follow an HTTP Redirect in Node.js?

Question

I want to open a page up in node and process the contents in my application. Something like this seems to work well:

var opts = {host: host, path:pathname, port: 80}; http.get(opts, function(res) {   var page = '';   res.on('data', function (chunk) {     page += chunk;   });   res.on('end', function() {      // process page   }); 

This doesn't work, however, if the page returns an 301/302 redirect. How would I do that in a reusable way in case there are multiple redirects? Is there a wrapper module on top of the http to more easily handle processing http responses from a node application?

Answer 1

If all you want to do is follow redirects but still want to use the built-in HTTP and HTTPS modules, I suggest you use https://github.com/follow-redirects/follow-redirects.

yarn add follow-redirects npm install follow-redirects 

All you need to do is replace:

var http = require('http'); 

with

var http = require('follow-redirects').http; 

... and all your requests will automatically follow redirects.

With TypeScript you can also install the types

npm install @types/follow-redirects 

and then use

import { http, https } from 'follow-redirects'; 

Disclosure: I wrote this module.
